Putting this out here!
Battle.net launcher causes freeze on the computer(nothing works), a manual restart is the only thing to do, doesn’t fix the problem.
Same problem for the US: https://us.forums.blizzard.com/en/wow/t/battlenet-launcher-crashing-and-freezing-pc/443915/51
apperantly for some Nvidia users it works to update their drivers, for others it don’t.
